NHTSA complaint #11112522, filed 2018-07, 139,000 miles“My navigation system screen stopped working while 1000 miles away from home. The biggest problem with the screen going out was the fact that all of the heating and air conditioning controls are ran through that same unit. Without being able to adjust my temperature in the vehicle I am not able to defrost the windshield in times when it may fog up.”

I cranked the vehicle up a few more times it was ok it turned on. Upon driving the vehicle had extremely unreliable acceleration , very had sputtering from and to stop lights this was from my commute to work.
